At the end of each chapter in your textbook, you will find a section called "Unit Review", answering the questions in this section will be a regular module assignment.
Although you may initially write your answers by hand, you will need to open a word-processing document, and then type in your answers to the questions so you can submit the file here by attachment.You should submit just one file with the answers to each chapter assigned within the module.
Read the assigned chapter- answer the Unit Review questions, submit all of your answers for the mod in one word file attachment.
Suggestion: Because you will may be assigned two or three units each module, you should plan to read a unit and answer those questions, then read each the remaining units and answer those questions as you complete each unit.
I will review your assignments and enter your grade in your Grades area in Canvas.
